成果简介	NOVELTY - The station (101) has multiple switched capacitors, switched capacitors (SC) based bidirectional multi-output AC-DC power factor correction PFC rectifier, where the rectifier is configured to operate a vehicle-to-grid mode, a grid-to-vehicle mode, a vehicle-to-vehicle mode and hybrid mode. The rectifier synthesizes seven levels at line voltage. Two DC-link capacitors (C1,C2) are configured to supply a neutral point for an output side, where each capacitor voltage is to-be-balanced at a desired voltage (VDC). Each phase of the rectifier is provided with a switched capacitor unit inserted between an AC source and a half-bridge. The switched capacitor unit is provided with four switches and two capacitors. Each half bridge in the rectifier comprises complementary functioning transistors in each phase. A circuit structure is configured to generate four levels as pole voltage and synthesize seven levels in the line voltages. USE - Charging station for charging an electric vehicle e.g. car. Uses include but are not limited to a hybrid electric vehicle (HEV), a plug-in HEV (PHEV), a hydrogen-powered vehicle, an alternative fuel vehicle (ESV) and a fuel cell vehicle, two-wheeler and lorry. ADVANTAGE - The station facilitates for causing a significantly less harmonic distortion, and embodies self-voltage balancing of the capacitors by the rectifier, and reduces number of sensors, and improves harmonic profile. DESCRIPTION OF DRAWING(S) - The drawing shows a circuit diagram of a charging station for charging an electric vehicle. 101Charging station for charging an electric vehicle 102Grid 103First electric vehicle 104Second electric vehicle 105Third electric vehicle 106Fourth electric vehicle
